A comparison of differential reinforcement and noncontingent reinforcement to treat food selectivity in a child with autism.

We compared differential reinforcement plus escape extinction to noncontingent reinforcement plus escape extinction to treat food selectivity exhibited by a young child with autism. The interventions were equally effective for increasing bite acceptance and decreasing problem behaviors. However, a social validity measure suggested that noncontingent reinforcement was preferred by the child's caregiver.

An analysis of modifications to the three-step guided compliance procedure necessary to achieve compliance among preschool children.

After a 3-step guided compliance procedure (vocal prompt, vocal plus model prompt, vocal prompt plus physical guidance) did not increase compliance, we evaluated 2 modifications with 4 preschool children who exhibited noncompliance. The first modification consisted of omission of the model prompt, and the second modification consisted of omitting the model prompt and decreasing the interprompt interval from 10 s to 5 s. Each of the modifications effectively increased compliance for 1 participant.

An evaluation of advance notice to increase compliance among preschoolers.

Advance notice of an upcoming instruction was evaluated to increase compliance among 3 children (4 to 5 years old) who exhibited noncompliance. Results show that the procedure was ineffective for all 3 participants. Advance notice plus physical guidance or physical guidance alone was necessary to increase compliance.

Further evaluation of antecedent interventions on compliance: the effects of rationales to increase compliance among preschoolers.

Functional analyses were conducted to identify reinforcers for noncompliance exhibited by 6 young children. Next, the effects of rationales (statements that describe why a child should comply with a caregiver-delivered instruction) were evaluated. In Experiment 1, 3 participants received the rationales immediately after the therapist's instruction.
